Sleeping Machine

For teenagers living in this period when technology impacts our daily life more than we thought, even affecting our sleeping qualities. To prevent teenagers from not having enough sleep while addicting to the mobile phone, this project could force them to turn off the light and have a good night's sleep. This original idea was from https://www.instructables.com/Sleeping-Alarm-Clock/ to innovate the functions, I added another LED light with flashing lights and slightly change the setting of other functions. For the appearance, I designed a different look with the look of an alarm clock.
